power regardlessof the direction of its rotary movement, and to lfurtherprovide a motor'wherein relative contact is maintained A between theabutment and rotor surface and vthe rotor surface and cylinder walls.

Further objects will be apparent from the disclosure in the followingspecification wherein is illustrated one embodiment of my invention, itbeing understood that various changes and modifications thereof may bemade in accordance with the scope of the appended claim.

To more fully comprehend the invention reference is directed to theaccompanying drawings, wherein Fig. 1 is a view in verticalsectionthrough one of the cylinders 'of my improved motor taken on line 1-1 ofFig. 3.

Fig. 2 is a view in end elevation of one of the cylinder end platesillustrating particularly the abutment groove therein.

Fig. 3 is a longitudinal sectional view taken on line 3-3 of theembodiment of motor illustrated in Fig. 1.

Fig. 4 is a view in perspective of one of.

the abutment bodies.

Fig. 5 is a view in perspective of one of the.

abutment shoes, and

Fig.`\6 is a view in verticalsection of one of the assembled abutmentbodies and shoes illustrating the location of the spring interposedbetween the same.

In the drawings, wherein corresponding parts are indicated. by likecharacters of reference, throughout the several views, 1rep resents thecylinder shells preferably annular in end e1evation.\ These shells arearranged in substantially end to end relation,

being separatedby a cylinder center plate 2 formed on its opposite faceswith recesses 3 in which are received the opposite edgesof the adjacentshells 1. The opposite ends of the shells 1 are closed by cylinder endplates 4 flanged at 5 to be received within the opposite ends of theshells.` The end and center plates are provided with aligned openingsI 6in whichvare received a rotor shaft'?, the same being supported at itsends in bearings 8,'stufling boxes 9 surrounding. the shaft iat.

its point of extension through end plate's'll. Keyed to the shaft andpositioned one within each shell between the center and the triangles of-adj acent rotors being opposite from each other approximately thirtydegrees. In each peak of the respective rotors forced outwardly by therespective springs 11 .are packing bars 12 contacting with the innerface of the respective Shells to prevent leakage at this point.

Each shell at its upper end is provided with a boss and upwardly andcentrally through the. same the bosses are vertically slotted as at 13to receive the body 14 of 75 an abutment reciprocably mounted therein.Each abutment body is provided with a stem 15 operating through a guide16 and stuffing box 17. The abutment bodies attheir ends and undersurface are channeled at 18 and within the same are received end members19 and base 20 of a substantially rectangular abutment shoe 25, theunder sur' face of which is rounded at 21, and is adapted to ride on theperipheral surface of the rotor 10. Springs 22 between the abutment bodyand shoe afford yielding movement between the same and maintain the shoesurface in contact with the rotor periphery at all times. -Pvotallymounted to a bracket 90 23 preferably on top of they motor structure isa lever 24, the bifurcated forked ends of which project on oppositesides of the stems 15 and receive the pins 26 on collars 27 secured tothe stems. that the uniting of the abutment'stems by the lever 24 andthe relative positioning of the rotors as in full and dotted'lines, Fig.1, causes the abutments `to closely follow the contour lines of theirperipheries and the spring held shoes on the respective abutment bodieswill compensate for the difference between the respective strokes of theabutmentand will at all times maintain theabutment edges in contact withthe rotorpe-v ripheries. The end and' center plates 2 and 4 are providedwith guide channels 28 for .receiving the end members 19 of the abutmentshoe asin Fig. 3 and affording guides for insuring the movement ofthesame in va predetermined path. ()neach side of the respective abutmentsin said-cylindersare It will be observed 95 sure, and with the outer endof each port.

connects a` tubular member 30, the supply of expansible Huid underpressure thereinto being controlled by a valve 31. The tubular member 30Abetween the valve 31 and the point of entrance of the port 28 into thecylinder is provided with a controllable vent valve 32.

The base of each cylinder is preferably provided with a vent opening 33,said openings being provided one on each side of vthe abutment and at apoint removed approximately 671/2 degrees from the port 29 on thecorresponding side of the abutment. The vents 33 preferably lead to theatmosphere through tubular hoods 34..

A fly Wheel 35 is illustrated as being mountedat one end of shaft 7, andat its opposite end the shaft preferably carries a power wheel 36. Aframe 37 aii'ords a support for the motor.

Thel parts being assembled, as in the draw'- ing, and the valve 31marked A being open -and the vent valve 32 marked B being triangles ofthe rotors approaching the op-v posite side of the abutment from that atwhich the valve A is located is vented through vent valve 32 marked B.It will be observed that, by offsetting the peaks of therotors asindicated in full 'and dotted lines, Fig. 1, an overlapping of powerstrokes is obtained and that the abutments are automaticallyreciprocated due t0 their connection by the lever 24.

To reverse the operation of the engine, it is only necessary to closethe valves A and B and to open the respective valves associatedtherewith which have heretofore y remained closed, and when thisoperation takes place, the shaft 7 will operate in a direction reverseto that indicated by the arrow C, Fig. 1 of the/drawings.

I claim z- A reversible rotary motor including a pair of cylinders, arotor in each, a shaft eX- tending through the cylinders and common tothe rotors, each of said rotors being substantially triangular in planand arranged and, keyed to the shaft with the peaks Oifset approximatelythirty degrees, an abutment reciprocably mounted ineach cylinder to rideon the periphery of the rotor, a ivotally mounted lever connecting the autments, each cylinder provided at opposite sides of and in closeproximity to said abutments with a valve controlled port for theadmission of an expansible fluid under pressure, said cylinders beingeach further provided with a pair of vents located one on either side ofthe abutments, each at ap-` proximately sixty-seven and a half degreesfrom one of said ports, and a controllable vent valve within eachadmission port between its point of entering the cylinder and itscontrol valve.

In testimony whereof I have signed my name to this specification.
